At the owners manual, it say to invert speakers polarity.
I doubt this is not applicable to St120 because of the preamp low gain card.
Am I right?
Best regards.

If your preamp does invert phase then the audio signal (out of phase) will be sent to your VTA amp. The out of phase signal will then be sent to your speaker outputs. As has been said above, all you have to do is reverse the two positive and negative wires on your speaker and your system will be in phase.

Wrong, else why would I hear a difference if BOTH sides are wired inversely?
I would say that if you cannot hear the difference and sounds good to you, that's all that matters.
A little googling on Absolute Polarity as it pertains to audio signals would help, I would post links but I'm too new
